Seven replacement parts here are listed as suiting A&L® windows and sliding doors. Two are patio door carriage and roller assemblies — a 25kg adjustable unit that also covers Boral® and Dowell® Mk5C and Wintec™ rollers, and a 32mm 40kg heavy duty adjustable carriage. The rest are the small things that strand a door or a screen: a sliding door bottom guide for screen doors, a non-keyed window catch and spring, and 8.7 x 38.7mm black flyscreen retaining clips, sold singly and in 10 packs. Worn rollers and perished clips are what bring these frames in. Pull the old part before ordering. On a carriage, measure the roller diameter and the carriage body — the 32mm in that title is the identifying dimension. On a clip, measure width and length against the 8.7 x 38.7mm listed.
